Title: Bowed stretching device and process particularly for stretching films of plastic in the elastic range
Inventor: STEFFL MANFRED DIPL ING
IPC: B29C48/355
Filed: 1988-11-04
Abstract: For stretching film webs of plastic in the elastic range, so-called bow or banana rolls are used. They comprise a flexible roll shell which is mounted by means of ballbearings and a fixed bowed support and is constantly driven by means of a friction drive. The structural complexity is enormous and the costs of such a roll arrangement are high. Partly due to the friction drive, wear is also high. A bowed stretching device of a comparatively much simpler structural design comprises a fixed bow element (1), which is provided with outlet openings (11) at least in the region of the angle of film contact. Air and/or gas or else liquid can be discharged through the said openings. As a result, a contactless air/gas cushion or a liquid film is thus built up. The bowed stretching device and the process for carrying out stretching are suitable in particular for stretching films of plastic in the elastic range. <IMAGE>

Title: Fibrous content sepd. from liq. manure by worm screen - is compacted into plug by worm screw occupying part of filter casing
Inventor: EICHLER DIETRICH DR
IPC: B30B9/12
Filed: 1989-08-03
Abstract: A power-driven worm within a cylindrical housing separates and compresses the solid content from liq. manure, produced e.g. in a pig raising establishment. After initial compression, the material passes along an intermediate cylinder section whose walls are porous, permitting discharge of the liq. fraction of the supplied manure, to be returned to the critical source. A later section of the cylindrical section, beyond the work turner, converts the compacted solids into a hollow cylindrical plug of manure. A hollow cylindrical auxiliary plug is inserted at the start of the sepn. zone. Torsion forces are adsorbed by bars axially engaging the sieve basket and holding the basket in housing slots. ADVANTAGE - Plug formation, conveyance and discharge against counter-pressure from sieve walls increases final solids content.
Patent DE-3926535-A1 (DE)
Inventor: HAEHNER MICHAEL DIPL ING
IPC: H04N5/60
Filed: 1989-08-11
Abstract: Due to the dimensions of the enclosure, determined by the picture tube, television receiving sets in most cases have too narrow a base width for radiating the stereophonic sound. To widen the base, it is therefore appropriate to connect external loudspeaker boxes. For receiving sets with integrated active boxes, a circuit arrangement is disclosed which allows passive wideband loudspeaker boxes to be operated externally instead of the set-internal loudspeakers, the transmission characteristics of the set-internal frequency-selective amplifiers being switched to wideband amplification with the aid of a separately operated switch or a socket switch. <IMAGE>

Title: Casting mould for thin walled hollow chocolate mouldings - has convex shaped foil cavity and upper filler opening, edge of which is bent inwards to form bulge on moulding
Inventor: LAEDERACH RUDOLF
IPC: A23G3/02
Filed: 1989-09-18
Abstract: The invention relates to a tool for prodn. of hollow chocolate mouldings which are required to be as thin as possible. The tool is made of foil and mouldings are released by shrinkage of the chocolate which is greater, the thicker the wall thickness is. To permit easy demoulding from the tool and also to improve strength in the weakest area of the mouldings i.e. around the opening for tool filling. A ring-like bulge is created in the moulding around the edge of the opening. The bulge is formed by bending the foil of the tool inwards to form a hook shape around the opening. Tool halves are formed with convex walls which meet without forming a ridge around the plane of largest dia. Only one half has a filler opening. USE/ADVANTAGE - Produces hollow chocolate mouldings, which have as thin a wall as possible yet have a stable filling opening and can be easily demoulded from foil tools.

Abstract: A plastic container 1 in the form of a crate, specifically in particular a storage and transport crate, is proposed, in which a bottom 4 having a flat upper side is stabilised on the underside by reinforcing ribs 5, 6, and in which flat webs 8 extend along the bottom edge 7 in the direction of the bottom plane, are supported with spacing below the bottom plane by reinforcing ribs 9 extending transversely to the bottom edge 7, and form the standing surfaces of the container 1.

Patent DE-4109401-A1 (DE)
Inventor: DENZ HELMUT DIPL ING
IPC: F02M25/08
Filed: 1991-03-22
Abstract: A process for alternating execution of phases with and without tank ventilation during the operation of an internal combustion engine (10) with a tank ventilator (21, 24-26) is characterized in that the ratio of the time-intervals with and without tank ventilation is chosen so that it is dependent on operating data of the engine or of the tank ventilator. Preferably the quantity measured is a measure of the quantity of fuel to be regenerated during tank ventilation, and the above-mentioned ratio is increased with respect to an initial ratio in favour of the tank ventilation time-interval if the value of the measured quantity exceeds an upper limit (Dp-SMW; FTEA-SWU). This process makes it possible to equip the corresponding device with an adsorption filter (24) and a tank ventilation valve (25) for smaller throughputs than hitherto, without the risk of fuel vapours escaping into the atmosphere. If large quantities of fuel vapor are produced, the tank ventilation time-interval is increased with respect to the basic adaptation time-interval. The smaller adsorption filter is therefore still adequately regenerated despite the smaller cross-section of the tank ventilation valve.
